SPECIFICATION forming part of Letters Patent No. 644,707, dated March 6, 1900.

Application filed October 5, 1898. Serial No. 692,717. (No model.)

To all whom it may concern:

Be it known that I, PETER F. GLAssBREN- NER, a citizen of the United States, residing at East Newbern, in the county of Jersey and State of Illinois, have invented a new and useful Churn, of which the following is a specification.

My invention relates to churns, and has for its object to provide a simple, compact, and efficient construction and arrangement of parts adapted for accomplishing speedily and with facility the separation of the butter and the simultaneous ventilation thereof to remove animal heat, and particularly to provide a rotary-body churn wherein a simple construction of operating devices is employed.

Further objects and advantages of the invention will appear in the following description, and the novel features thereof will be particularly pointed out in the appended claim.

In the drawings, Figure l is a perspective View of a churn constructed in accordance with my invention. Fig. 2 is a vertical central section of the same.

Similar numerals of reference indicate corresponding parts in both figures of the drawings.

In the construction illustrated in the drawings the supporting-frame consists of a base l, from which rise the standards 2, connected by suitable cross-bars 3, said base being provided at its center with a stub-spindle 4, upon which is seated the lower end of the rotary churn body or receptacle 5, said body or receptacle being provided at the center of its bottom with a socket to receive said stubspindle. The receptacle is fitted with a removable lid or cover 6 and may also have a valved drain-outlet 7 and an inspection-pane 8, said lid being provided at its center with a casting 9, in which is formed an angular seat lO for the reception of the lower extremity of the angular hub ll of the pinion l2. This pinion, with its hub, is mounted for rotaryand axial movement upon a dasher-staif 13, which extends below the lower end of said hub ll and through an opening in the lid or cover of the churn and carries a dasher 14. The upper end of the dasher-staff is removably iitted in the opening 15, formed in a support 16, overhanging the base of the supporting-frame and composed of a pair of brackets and a horizontal rod, and in practice I prefer to secure said shaft against rotation by engaging therewith a transverse pin or key 17, suitably seated in the support in an opening transversely intersecting the opening 15. The rod is extended beyond the opening l5 to form a stub-shaft 18, upon which is mounted a drivinggear 19, meshing with the pinion I2 and adapted to be driven by any suitable means, as by a crank-handle 20. The rod is iiXed to one of the brackets and extends through an enlarged bearing of the other bracket.

It is obvious that by the rotation of the driving-gear motion may be communicated .through the pinion to the churn body or receptacle while the dasher is held stationary to cause the desired agitation of the contents of the receptacle, and in order that thechurn body or receptacle may be readily dismounted to give access to its interior and for analogous purposes I preferably secure the driving-gear upon the stub-shaft 1S in such a way as to provide for its movement outwardly from the plane of the pinion l2, as by fitting said stub-shaft with a removable key 2l.; Having displaced the driving gear, the pinion, with its angular hub, may be moved upwardly upon the dasher-stafl 13 to disengage the lower end of this hub from the seat in the lid or cover of the churnerec'e ptacle, whereupon said lid or cover may be raised, or the receptacle may be lifted sufficiently to dismount it from the stub-spindle on the base of the frame. Furthermore, it will be seen that when the parts of the driving mechanism are in their operative positions the downward pressure of the pinion l2 and its hub is adapted to maintain the churn lid or cover firmly in place, and thus prevent the liquid contents of the receptacle from escaping between the lid and the edge of the receptacle. Also carried by the churn body or receptacle, and preferably `by the lid or cover thereof, are Ventilating devices consisting of an inlet-tube 22 and an exhaust-tube 23, the former being provided with a deflecting-hood 24, facing in the direction of rotation of the5 churn body or receptable, and hence adapted to catch the air TOO during such rotation and force it downwardly into the churn-receptacle, where it is brought into contact with the liquid contents thereof. The exhaust-tube is adapted to allow the escape of air after it has performed its ventilating function to carry o odors, and thereby accomplish the purification of thermilk. Said exhaust-tube is also preferably provided at its upper end with a funnel-mouth 25 to facilitate the introduction therethrough of Water in the process of separat-in g and clean sing the butter.

From the foregoing description it will be Seen that I have provided a churn mechanism wherein the operation of the movable part, consisting of the churn body or receptacle, is accomplished by means of two gears, preferably mounted with their axes at right angles and each capable of axial ,movementto facilitate the dismounting of the churn body or receptacle, which when the parts are in their normal positions is held rmly seated, with its lid or cover secured in place by the pressure of one of said movable gears. Furthermore, it will be seen that I have provided, in connection with a rotary-body churn, means for Ventilating the contents of the receptacle, the introduction of air being accomplished by the rotation of the body, and thus dispensing with auxiliary mechanism, such as blowers or theequivalentthereof. Itwillbeunderstood, furthermore,that various changes in the form, proportion, and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

Having described the invention, what I claim, and desire to secure by Letters Patent, 1s

A churn comprising a frame provided atits bottom with a stud, a rotary churn-body pivotally mounted on the said stud and provided at its bottom with an interior vertical pivot, the vertical rod 13 mounted on the pivot, a cover arranged on the churn-body and having an opening to receive the rod 13, the plate secured to the upper face of the cover and provided with a socket, the pinion 12 arranged on the rod 13 and provided with a depending hub 11 detachably interlocked with the socket of the plate and serving as the means for retaining the cover on the churn-body and adapted to be readily removed from the former, a bracket arranged at each side of the top of the frame, a horizontal rod ixed to one bracket and extending through an enlarged bearing of the other, said rod heilig provided at the inner end of the enlarged portion with an opening receiving the upper end of the rod 13, a slidable sleeve arranged on the rod and extending through the enlarged bearing of the adjacent bracket and provided at its outer end with a handle, a gear-wheel 19 earried by the inner end of the sleeve and meshing with the said pinion, and means forlocking said sleeve on the rod, substantially as described.

In testimony that I claim the foregoing as my own I have hereto aixed my signature in the presence of two witnesses.
